BELT-GUIDE.

SPECIFICATION forming part of Letters Patent No. 768,213, dated August23, 1904. Application filed February 16, 1904:. Serial No. 193,821. (Nomcdel.)

To all whom it may concern:

Be it known that I, HERMAN W. BRUTLAG, a

- citizen of the United States,.'residing at Fulda,

in the county of Murray and State of Minnesota, have invented certainnew and useful Improvements in Belt-Guides, of which the following is aspecification. I

My invention relates to belt-guides for general purposes, but moreespecially to that class of belt-guides designed for use onthreshingmachines or other mechanism usually operated in the open fieldor out of doors; and the objects of said invention areto provideasim-.ple and inexpensive device for preventing driving-belts from runningoff their pulleys when exposed to high winds or under any circumstanceswhich have such tendencies.

The objects referred to are attained by means of the constructionillustrated in the accompanying drawings, in which- Figure 1 is asideview of a belt-guide made in accordance with my invention.v Fig; 2 is aview in partial section of one-half of the beltguide,'as shown inFig. 1. V

The numeral 1 designates the base or support for the belt-guide, andthis base may be provided with screws or bolts 2 for securing the guidein place along the line of the belting. Extending above the base 1 is abearing-block 3. having inclined sockets or bores 4 for the axles orstub-shafts 5.

set screws or pins 6.

Since the construction of each half of the belt-guide is the counterpartof the other half, a description of one half will suflice for both.

The beveled idler or belt-support 7 is journaled,

idler 7 the shaft 5 is provided with an enlarge-' ment 9, and extendingvertically from this enlargement and formed integrally therewith is apintle or shaft 10 for the keeper-roll 11 and the edge bearing-hubs 12.The keeperroll 11 has a beveled periphery 13, and a beveled pulley 14 isjournaled to freely revolve on the pintle 10 under the roll 11, a nut 15being used to hold the two rolls in place.

These stub-- shafts are rigidly secured in the sockets 4 by The hubs 12are integral with the beveled pulleys 14:, and similarbhubsare formed onthe keeper-rolls 11. The pulleys 14 and the rolls 11 are free to revolveindependently on the pintle 10. The belt-support or idler 7 is providedwith a groove 18in its upper surface to give room for the beveled edgeof the pulley 14:- Two handoilers or oil cans 17 may be held inconvenient place for use on the guide by means of two perforations inwhich the tubes of the oil cans may be inserted. These oil-cans may bereadily removed from the perforations whenever it is desired to use themabout the machinery.

From the foregoing it will be obvious that a belt leading from thedriving-pulleys of a machine may be passed between the idlers 7 and thekeeper-roll 11, and the belt will be prevented from running oif thepulleys, the edge of the belt running against the hubs 12 and verylittle friction being created between the belt and guide.

1 Having thus fully described my invention, what I claim is 1. Abelt-guide comprising a base having inclined sockets, shafts mounted inthe sockets, beveled belt-supports mounted to revolve shaft,substantially as described.

2. A belt-guide comprising a base having inclined sockets, shafts fittedin the sockets, beveled idlers journaled to revolve on the shafts,bearing-balls for said beveled idlers, there being enlargements on theshafts above the idlers, beveled rolls, journaled on vertical pinsextending from the shafts, the idlers each, having a groove to admit thebeveled edge of the lower beveled rolls, substantially as described.

In testimony whereof I afiix my signature in presence of two wltnesses.

HERMAN W. BRUTLAG.
